A man had x amount of money. He went to the temple and his money doubled . He gave 100 back to the temple .This happened the next 3 time . At the end of the day he had 0 money . What was his initial amount

initial amount = 93.75  Step-by-step explanation:  Initial amount with the man = x After his first visit to temple, his money gets doubled, So now, present money that the man has = 2x after he gives 100 back to the temple, money left with the man = 2x - 100  This happened 3 more times,  So money after 2nd visit = 2(2x - 100) = 4x - 200 money after giving 100 to the temple = 4x - 200 - 100 = 4x - 300  So money after 3rd visit = 2(4x - 300) = 8x - 600 money after giving 100 to the temple = 8x - 600 - 100 = 8x - 700  So money after 4th visit = 2(8x - 700) = 16x - 1400 money after giving 100 to the temple = 16x - 1400 - 100 = 16x - 1500  Now, at the end of day, he is left with 0 money which means that, 16x - 1500 = 0 16x = 1500 x = 93.75
